How to overload operator= to have both deep copy and shallow copy semantics

[bluekite2000]

In other words

Array<int,1> A(5), B(10);
A = B(Range(0,4)); // Statement 1
Array<int,1> C = B(Range(0,4)); // Statement 2

I d like
Statement 1 results in a portion of B's data being copied into A
and
After Statement 2 is executed, the array C is a reference (or alias) to
B's data.

Here operator= is *not* used. It's called _initialisation_ and *not*
assignment. Overloading the assignment operator won't help you. You
need a proper constructor for that.
